T0 at whom it may concern.-

Be it known that 1, WILLIAM DICKS, a subject of the Queen of GreatBritain, having declared my intention to become a citizen of the UnitedStates, residing at Kensington Station, Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Screw-Wrenches, of which the following is a specification.

My invention relates to certain improvements in screw wrenches, also tocertain details of construction, all of which will be fully and clearlyhereinafter described and claimed, reference being had to theaccompanying drawings, in which- Figure l, is a side elevation ofmyimproved wrench, showing the jaws of the wrench partly opened, therebyexposing a portion of a screw driver combined with it, and in positionfor use. Fig. 2, represents a similar view of the screw driver, showingthe jaws closed andthe end of the screw driver drawn within the handleout of sight. Fig. 3, is a back view of the wrench, showing the jawsopen and the screw driver exposed. Fig. 4:, is a detached side elevationof one half of one of the movable jaws, showing its construction. Fig.5, is a rear View of the movable jaw shown in Fig. 4, one half beingshown by dotted lines. Fig. 6 represents a cross section through thehandle of the wrench cutting centrally through the depression 10 andopening 9 The object of my invention is to simplify the construction ofthe wrench so it can be more cheaply made, also in combining a screwdriver with the movable jaw of the wrench.

Referring to the drawings, 1 represents the handle of the wrench, 2, theportion upon which the movable jaw slides back and forth, and 3represents the stationary jaw, the whole being formed in one piece ofwrought metal, drop forging preferred, but if desired cast malleableiron, or cast steel may be used. The stationary jaw being formed in onepiece with the slideway portion and handle it would be impossible to getan ordinary sliding or movable jaw over either the handle or stationaryjaw. I therefore form the sliding jaw of my wrench in two parts, 4 and4*, see Fig. 3, also Figs. 4 and 5. These jaws are pref erably made bydrop forging, the half portions being rights and lofts, substantially asindicated in Fig. 5. These portions at and 4, are fitted together overthe shank or portion, 2, uponwhich it slides back and forth, and arethen riveted securely together by rivets, 5, and are fitted so as toslide easily along the sliding portion, 2.

To the sliding jaw, 4 and 4 is rigidly secured a screw bar, 6, by a pin,6*, having its' screw portion, 7, extending from the end, 1', (whichscrews into the sliding jaw and is secured by the pin, 6,) to or aboutthe point, 7. From the point, j, it extends down and terminates in ascrew driver point, 8. The screw bar, 6, passes through a longitudinalhole, 8,- extending clear through the handle 1. The hole, 8 is shown bydotted lines, 8 in Figs. 1 and 2.

Before the screw bar, 6, is secured by the pin, 6, to the sliding jaw,acylindrical milled nut 9, is put into an opening, 9, in the haudle so asto be in a line with the hole, 8, so that the screw bar can be screwedthrough the nut and then forward far enough to allow the end to bescrewed into the movable jaw and be secured by the pin, 6.

It will be noticed that the portion of the handle, 1, is hollowed out sothat a depression 10, surrounds the opening, 9*. The object of this isto allow more room for operating the milled nut, 9.

In my device the screw driver is drawn up within the handle at the sametime the jaws are brought together, thereby reducing the length of thewrench and leaving everything .drawn closely together and the length ofthe wrench reduced so that it is in a better condition to pack away insmaller space when not required for use. I obtain this result by makingthe outer jaw the fixedjaw, forming a part of the shank or slidewayportion 2, and the handle 1, and connecting with the inner jaw whichmoves on the shank 2, the screw bar 7 having the screw driver portion atits opposite or free end.

I claim as my invention-- 1. In a screw wrench, a handle, a slidewayportion and a fixed or stationary jaw all formed in one piece, thehandle being set partly to one side of the slideway portion, incombination with a movable jaw mounted on the slideway portion, a screwbar passinglongitudinally above the slideway portion and through thehandle, a screw driver portion at the free end of the screw bar andhaving its opposite end secured rigidly to the movable jaw, a milled nutmounted on the screw portion of thescrew barwithin an openingthrough thehandle, for operating the screw bar, the movable jaw and the screwdriver, whereby the screw driver is exposed when the jaws of the wrenchare separated and is drawn in place within the handle when the jaws aretogether, substantially as described.

2. In a screw wrench, a stationary or fixed jaw, a slideway portion anda handle all formedin one piece, in combination with a movablejaw formedin two parts adapted to be united on the slideway portion and rivetedtogether, a screw bar rigidly secured to the movable jaw and a nutmounted on said screw bar within an opening in the handle, substantiallyas and for the purposes described.

3. A screw wrench consisting of a handle, a slideway portion and a fixedjaw, all formed in one piece, the handle being to one side of theslideway portion, a screw bar passing longitudinally through the handleand rigidly connecting with the movable jaw, an opening through thehandle, a depression surrounding said opening and a cylindrical nutmounted on the screw bar within the opening in the handle substantiallyas and for the purposes described.
